Abstract

PROBLEM TO BE SOLVED: To provide hot water using exhaust heat as a heat source by constituting a water passage by bring a pipe into contact with a part of the exhaust side of an automobile and passing water through it, installing a water storage tank and changeover valve in the water passage, and mounting a discharging side water passage in the changeover valve. SOLUTION: A pipe 13 forming a water passage made with a copper pipe is connected to a water storage tank 12 at its both ends and is wound around an automobile exhaust side 11 at its intermediate part, and a heat-resistant sheet 14 is mounted outside the automobile exhaust side 11 and the pipe 13 wound around the automobile exhaust side 11. The pipe 13 is extended by joints 15 on its way, the water storage tank 12 and a changeover valve 20 are placed in a water passage of such pipe 13, a discharging side water passage 21 is mounted in the changeover valve 20, and when hot water is used, the changeover valve 20 is switched to introduce hot water heated on the automobile exhaust side 11 into the discharging side water passage 21.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an apparatus for producing hot water for an automobile. More specifically, the present invention relates to a hot water production apparatus for an automobile that produces hot water using exhaust heat of an automobile.

[0002]

2. Description of the Related Art Conventionally, when a user of an automobile such as a camper gets hot water for showering, hot water is separately obtained by using a heat source such as gas or electricity.

[0003]

When a heat source such as gas or electricity is separately used, it is necessary to mount the heat source on an automobile. Also, the exhaust heat was left without any particular use.

[0004]

Means for Solving the Problems The present invention provides

[0005] A pipe which constitutes a water passage by bringing a part of the water close to the vehicle exhaust side and allows water to flow inside, a water storage tank installed in the water passage, a switching valve installed in the water passage, and a switching valve And a drain-side water passage attached to the vehicle. The cold water in the water passage is heated by the heated automobile exhaust side.
The heated hot water circulates in the water passage and is stored in the water storage tank. When using hot water, switch the switching valve,
Introduce warm water into the drainage channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 showing a front view of an embodiment of the present invention, FIGS.
An embodiment of the present invention will be described with reference to FIG.

Reference numeral 11 denotes a vehicle exhaust side, which in this embodiment comprises a muffler for a vehicle such as a camper. 12 is a water storage tank and 16 is a water supply port. The water storage tank 12 is installed outside a vehicle body such as a camping car or indoors. 13 is a pipe. The pipe 13 is formed of a copper pipe in this embodiment and forms a water passage. Both ends of the pipe 13 are connected to the water storage tank 12, and the middle part is wound around the vehicle exhaust side 11. 1
Reference numeral 4 denotes a heat-resistant sheet, which is installed outside the automobile exhaust side 11 and the pipe 13 wound around the automobile exhaust side 11 to prevent the exhaust heat from being transmitted to the outside. 15 is
It is a joint and connects the pipe 13 on the way. In the water passage composed of the pipe 13 and the water storage tank 12,
Install a circulation pump.

Reference numeral 17 denotes a float which is installed in the water storage tank 12, and stops the operation of the circulation pump when the amount of water in the water storage tank 12 detected by the float 17 is less than a predetermined amount. Reference numeral 18 denotes a thermometer, which is installed in the water storage tank 12 and measures the temperature of circulating water in the water storage tank 12. 19
Is a water meter, which is installed in the water storage tank 12 and allows the amount of circulating water in the water storage tank 12 to be visually recognized from outside.

Reference numeral 20 denotes a switching valve, which is installed in the water passage. Reference numeral 21 denotes a drain-side water passage attached to the switching valve 20.

The cold water in the water passage is heated by the heated automobile exhaust side 11. When the heated hot water rises to a predetermined temperature, it is circulated in the water passage by the circulation pump and stored in the water storage tank 12. When the temperature of the water in the water passage is lower than the predetermined temperature, the operation of the circulation pump is stopped as shown in FIG.

When using hot water, the switching valve 20 is switched as shown in FIG. 3 to introduce hot water into the drain side water passage 21.

[0012]

Therefore, in the present invention, the exhaust heat of an automobile that has not been used conventionally is used as a heat source,
It has become possible to obtain hot water without additional heat sources.
